Description

ESI ESI-U108 Overview

The ESI U108 PRE is a high-speed USB 2.0 audio interface offering ten mic preamps, eight line outputs, and 24-bit / 96 kHz resolution, making it ideal for recording bands in the studio, live performances on stage, or multi-guest podcasts at home. Connect instruments such as guitar and bass to the two front-panel combo jacks, then select the Hi-Z switches for optimal signal transfer. A total of ten XLR inputs (two via the combo jacks) are provided, and selectable phantom power ensures proper operation of condenser microphones as well as dynamic mics.

Utilize the eight 1/4″ TRS line-level outputs to route submixes or individual tracks to a console, summing mixer, or multichannel headphone amplifier. Hook up a pair of monitors and headphones to the U108 PRE’s 1/4″ mix outputs and stereo headphone jack. LEDs across the front panel clearly indicate input levels, phantom power selection, and power status.

The U108 PRE is compatible with Mac and Windows computers and includes a power adapter and one USB cable. Bundled software and licenses from Bitwig, Stanton, and Audified open creative opportunities for musicians, DJs, and podcast producers.
